It’s claimed the two clubs agreed on a fee of £8m for the 29-year-old Belgium international whose contract expires in June 2018.
Jose Mourinho wants to strengthen his squad but the Red Devils hierarchy decreed the Portuguese cannot add to the wage bill without selling first.
The news comes soon after Fellaini was singled out for praise for his performance at Stamford Bridge during a damaging 1 – 0 defeat to Chelsea.
The Belgian’s style adds strength to United’s midfield but with Paul Pogba, 24, returning to first team action in the 4 – 1 drubbing of Newcastle United at the weekend, Fellaini’s chances of regular football are limited.
Signed from Everton in a £27.5m deal in 2013 when David Moyes took over at Old Trafford, Fellaini fell from grace with Scot’s successor Louis Van Gaal in 2014. The Dutchman saw the Belgian as a striker but the switch to a more advanced role did not work out. Fellaini found himself left out of the side more frequently and ended the season with just 18 league appearances to his name.
He appeared to be working his way back into Mourinho’s favour with starring roles in the club’s Europa League run last season.
However, Pogba remains – unsurprisingly – as the Portuguese first choice and Fellaini is desperate to retain his place in Roberto Martinez’s Belgium plans. A move to the Super Lig champions would give him a better chance of cementing his place in the Russia 2018 World Cup squad.
